In a medium bowl, sift dry ingredients together. In a slightly larger bowl, whisk together crushed pineapple, flax eggs, olive oil, and grated ginger. Add the dry ingredients all at once, and stir until just combined. Add grated carrot, stirring to distribute evenly through the batter. Spoon into prepared muffin tins. Bake for 30 min, rotating the tins half way through. Gently release the muffins from the tins, and turn onto their sides in the tins to cool.
